Striker assemblies and latch assemblies are disclosed. One striker assembly includes a housing, a striker, and a spring. The housing has opposed sidewalls, each of which defines an aperture. The striker extends between the sidewalls of the housing with end portions of the striker positioned within respective apertures defined in the sidewalls. Each of the pair of end portions defines a surface extending in a transverse direction. The spring has a pair of end portions. Each spring end portion contacts the surface of a respective striker end portion. The spring is engaged with the housing to bias the end portions of the striker toward a centered position of the respective apertures. At least one of the end portions of the striker is movable transversely within the respective aperture away from the centered position of the respective aperture and is biased toward the centered position of the respective aperture.

A locking lever includes: a pair of lever pieces connected to each other to be relatively rotatable; and a spring member which extends about rotating axes of the lever pieces, of which both end portions engage with the lever pieces, and thereby, which biases the lever pieces to rotate in opposite directions, wherein contact portions, which come into contact with each other based on a biasing force of the spring member and thereby, are able to hold relatively rotating positions of the lever pieces, are provided in the lever pieces, respectively, wherein the spring member has spring end portions extending in a radial direction of the rotating shaft, and wherein an engagement surface with which the spring end portion comes into contact in a circumferential direction of the rotating shaft is provided on at least one of the lever pieces.

A status indicator for a locking mechanism may include a status indicator face, a status indicator plate, a cam coupling, and a locking mechanism coupler. The status indicator face and status indicator plate may be at least partially moveable relative to one another. The locking mechanism coupler may have a greater rotational range of motion than the cam coupling. The status indicator face may indicate the state of a locking mechanism and may have a viewing angle greater than or equal to 180 degrees.

Disclosed are door locks that include a spring based position securing system for a locking or anti-theft device. The spring may be a dual-acting clamping spring. Also disclosed are methods for producing door locks that include the spring based position securing system.

Provide a door latch apparatus with a childproof lock mechanism that is only a projecting portion of the childproof lock mechanism is movable in the release direction interlocked with an opening operation of an inside lever, so that the degree of freedom of arrangement and design of several kinds of parts assembled in a housing can be increased. A release actuating member is supported movably in an elongated guide hole of a childproof lever from a standby position to a release position. When the childproof lever is in a childproof unlocking position and when an inside lever is carried out the opening operation, a projecting portion contacts to the inside lever and moves in the opening direction, so that the release actuating member moves to the release position against a biasing unit.

A lever-lock release system is configured to releasably couple two objects together, for example a parachute and a payload. The lever-lock release system may comprise a first lever and a second lever, each rotatably coupled to a rigid base. When activated, the levers cascadingly rotate to release a first object and a second object. With these systems and related methods, various failure modes may be eliminated, such as undesired premature deployment of recovery parachutes during aerial delivery.

A spring cartridge for a mortise lock for engaging first and second spindle hubs rotatable by a handle to open and close a latchbolt. The spring cartridge comprises a housing adapted to be secured within the mortise lock housing, and first and second members slideable with respect to the spring cartridge housing, the first and second members each having a first end adapted to contact an outer surface of the first and second spindle hubs, wherein the first and second members are independently actuable along a longitudinal axis of the spring cartridge housing in response to rotation of the first or second spindle hub. A spring retained by the spring cartridge housing contacts a second end of the first and second members to bias each of the first and second members against the outer surface of the first and second spindle hubs, respectively. Upon rotation of one of the hubs, the member contacting the hub permits the hub to rotate, while the member contacting the other hub prevents the other hub from rotating.

The invention relates to a motor vehicle door lock comprising an actuation/locking lever mechanism, with a first lever and a second lever, both levers being couplable with each other in at least two different relative positions. At least the one, first lever comprises a detent spring connected thereto for engagement with at least one detent recess on the other, second lever.

A lock device is provided with: a latch unit having a slit which allows a striker to enter and exit and configured to engage with and to be disengaged from the striker; and a support member for supporting a spring member outside the latch unit in such a manner that the spring member extends in the width direction of the slit. The spring member is elastically deformed when in contact with the striker having entered the slit, and as a result, the spring member applies pressing force to the striker, the pressing force acting in the direction in which the striker exits the slit.
